Technical scheme of the present invention can be expressed as Fig. 1, and concrete steps are as follows:
Comprise towards enterprise's application deployment of many tenants and management system: routing layer, apply runtime layer and service layer.Each level is constructed as follows:
● routing layer: Router, Control, LoadBalance;
● application runtime layer: NodeAgent, Container, AppMaster, AppSVN, Monitor, IAASAdaptor;
● service layer: infrastructure service (database, buffer memory, message), Integration Services (third party's service).
The core component of described system comprises with lower part:
(1) cloud route (Router)
The function of cloud route comprises load balancing, route, Flow Record etc., can be divided into three levels:
● adaptation frameworks: provide service adapter engine flexibly, can perform flow process by orchestrating services, and can increase COS newly easily;
● infrastructure service: the infrastructure service such as service routing, load balancing, traffic statistics, access control, abnormality processing, flowing water service is provided, the timed task infrastructure service for particular request is also provided;
● protocol adaptation: with other modules provide communications protocol alternately, comprise asynchronous HTTP and pick out agreement, JMS agreement etc.
(2) access control (Control)
The function of access control is the access control policy issued according to AppMaster, judges whether to allow request to continue access application.Access control to as if application, can be learnt by collocation strategy and apply when denied access.After user asks to arrive router, conduct interviews according to the apply names that will ask and control to check, and tackle at router, avoid the request of certainly denied access application to enter Node.Access control policy tentatively comprises the entry-into-force time section of application.
(3) cloud load balancing (LoadBalance)
The function of cloud load balancing comprises state acquisition, weight computing, load distribution.First, application state and node state, then calculated examples weights are obtained from NodeAgcnt.After Router transmits load balancing requests, distribute load according to example weights.Weight computing strategy is divided into static policies and dynamic strategy:
● static policies: all examples according to 1: 1 ratio poll;
● dynamic strategy: according to weight computing strategy, is converted to application weights application state, wherein, weight computing consider because have, node average response time, cpu busy percentage, linking number etc.
(4) cloud node-agent (NodeAgent)
The function of cloud node-agent comprises:
● realized the escape of management platform order by NodeAgent, shield the difference of operating system and the difference of container, be communicated to application and service;
● according to the order of management platform resource isolated according to demand or share;
● the resource taken node resources information and application or service carries out detection and the transmission of definable frequency.Wherein, node-agent and resource information detecting function mainly comprise:
● create LXC resource isolation container
The demand transmitted according to AppMaster according to, formulate maximum memory number and take number, formulate core cpu number, create LXC resource isolation container.Allly be deployed in application in container or service, the exclusive internal memory that distributes and cpu resource after container starts, realize applying with other and the resource isolation of example.
● delete LXC resource isolation container
After receiving the unloading order of AppMaster transmission, the application disposed in unloading LXC resource container or service, and complete the release of shared CPU, internal memory, hard disk resources.
● obtain application/service installation kit
Disposition Instructions is assigned by AppMaster, authorization information required for Disposition Instructions obtains as, user name, password, and installation resource bag position, then by FTP, HTTP and the mode sharing the direct remote copy of storage, the active obtaining of resource is carried out.
● monitoring resource
Node running status is provided according to self-defined frequency acquisition, wherein, cpu busy percentage, residue physical memory number provides application/service state according to self-defined frequency acquisition; Cpu busy percentage, physical memory takies number, and linking number collection adopts periodic synchronous collection, changes the mode triggering active acquisition carry out monitor message and gather with running status.
● snapshot functions
After application or service arrangement complete, the state applied or serve and information are mapped in physical store from internal memory, again map when state changes.When node is restarted, or can according to SNAPSHOT INFO after dynamic transfer, will to apply with service recovery to deployment success state, and carry out calling or reclaiming for AppMaster.
(5) application container (Container)
Support multiple application container and service container, the application that other program languages compatible are developed and service, support each version application server based on jetty and tomcat.Support that OSGI container is service container, and spare interface other containers compatible are as Weblogic, TongTech etc.Master transmitting order to lower levels, NodeAgent resolves the instruction that Master order formation agent node can identify, the container needed for Java is not only supported in these instructions, also can expand compatible container required for other language.NodeAgent itself does not have being coupled of any speech level with the container supported, undertaken alternately by these compatible command N odeAgent and institute's agent node, and then the resource in distribution node, carry out the deployment of application on node or service, to the control of the application disposed or service.
(6) cloud management (AppMaster)
The application of trustship is mainly divided into two types, and one is Web application type, and another is COS.Web application type is the B/S system or website that directly can be accessed by browser, and COS is for providing the system of some functional interface.This two type corresponds to application and service respectively in platform.Managed by cloud, bookkeeping can be carried out to application and service, comprise deployment, startup, stopping, unloading, isolation etc.After application or service start, this application or service can be accessed by Router, and can arrange can access time section (access control).The application and service started also can carry out the instance number of dynamically adjust operation according to the flexible strategy of the running status of reality and setting.Load is excessive when running, then can expand example and carry out equally loaded, when load declines, also unnecessary instance number can be stopped or destroying.
(7) cloud storage (AppSVN)
AppSVN is responsible for the warehousing management of application resource bag, and major function comprises, and application resource is uploaded, and application resource is audited, application resource version management, and application resource stores, Query Resource Information, generates and disposes bag.After application developer develops application with reference to application and development specification, " application resource strapping tool " can be used to create out the application resource bag meeting system requirements, then by application resource upload function resource wrapped and pass in AppSVN, and relevant resource version information is set.When developer is ready to application resource to be deployed in platform, the resource version of needs can be submitted to platform management person's examination & verification, not audit or audit unsanctioned application resource, application or service unit can not be registered as.
When user is after AppMaster registered application or service unit, the particular version being associated with certain resource is needed to dispose.Management resource is also selected to run container, and generation application resource is disposed bag by AppSVN, and in application deployment process, this deployment bag can be obtained by NodeAgent and for disposing.AppSVN also manages application resource and runs container, can upload new container or upgrade container version.
